Description
The present invention relates to a kind of preamble according to claim 1, for manual transmission, such as the Effector utilizing line traffic control to shift gears of automatic transmission.
The manual transmission of automobile usually controls by the Effector be arranged in the operating range of driver or switches.Usually, use the control member of such as speed change lever or gear level, between the front row seat that they are such as arranged on automobile for this reason.
Diversified to this Effector of manual transmission or the requirement of gear level at this in structure and in ergonomics.Such as, for the reason of safety and man-machine harmony, in order to the truly feels of speed-changer operation are informed to driver, Effector for described type proposes following requirement: no matter will be the feedback of vision or the feedback of clear and definite sense of touch or stereognosis about the current switching of speed changer or working state, all inform to driver.
According to having the state of manual transmission to be operated and according to other status consideration on automobile-be placed in igniting, motor operation, car speed etc.-be such as usually the necessary maneuvering area by concrete condition restriction gear level, stoping driver to select such as temporary transient unallowed switching state or the travelling speed level of manual transmission thus.
Current most of automatic transmission all belong to the manual transmission of line traffic control, particularly for the manual transmission of described line traffic control, for man-machine harmony and safe reason, require at this: not only informed temporary transient unallowed switching state by vision but also by sense of touch to driver, the form of informing is the relative operating position of correspondingly locking gear level.
On the contrary, when the former common speed-changer operation of pure machinery or the machinery between gear level and manual transmission are coupled-such as by tackle block or connecting rod-, because the machinery between gear level and speed changer is coupled, shift lever position is natively consistent with the gear box position of reality all the time, and the possible manipulation locking in speed changer is also felt on gear level by mechanical transmission is direct straight from the shoulder.
But day by day adopting in electrically-energized situation, or when line traffic control handle manual transmission, no longer there is machinery between the automotive transmission in the control member in main cabin or gear level and motor room and be coupled.Or rather, for " line traffic control " speed changer, switching command transmission from Effector to automotive transmission, in most cases by means of only electricity or the signal of electronics carry out, and next in most cases on speed changer itself, carry out electro-hydraulic switching command conversion.This point had partly both been applicable to modern manual transmission, but was specially adapted to the speed changer in the present age automatically, and contemporary speed changer great majority have compact final controlling element, and can remote control.
But in the manual transmission situation that line traffic control is handled, owing to lacking mechanical connection between speed-changer executing mechanism and gear level, can cause-cannot be reacted on by changer lever again based on the switching locking of current automobile or transmission state-such as insert in the transmission the state of gear level.Driver thus can not straight from the shoulder by certain can feel on gear level identified by the switching position of locking: corresponding travelling speed level or transmission state are such as unallowed under temporary transient travelling state, or can not be selected.
Attempt adopting following measure to solve this problem: the gear level of the manual transmission of line traffic control is provided with the various different final controlling element for the unallowed switching command of locking selectively.These final controlling element activate according to automobile or transmission state, to limit the initial whole moving region of gear level according to temporary transient traveling or transmission state thus.
But this point has following shortcoming: the installing space in gear level region prespecified for this multiple final controlling element cannot be provided use straight from the shoulder.In addition, the final controlling element of this in most cases electromagnetism has heavier quality due to the copper winding wherein existed, and this causes the weight of switching unit undesirably to increase.Particularly multiple independently final controlling element also causes constructions cost to increase, and then causes the cost of switching unit to increase.With regard to pursue increasingly reduce consume with regard to, the impact that can not be ignored also is played in energy ezpenditure and the heat radiation related to this of this final controlling element.
Under this background, the object of the invention is, propose a kind of Effector with lockable mechanism, its especially for electricity ground or electronically line traffic control handle manual transmission, and utilize this Effector can overcome the aforesaid drawbacks of prior art.Especially, under lock assembly complicated situation, lockable mechanism adopts the final controlling element of the least possible quantity also should be enough to deal with, thus particularly weight, installing space, energy ezpenditure and cost-when reliable in function-reduced.
This object is achieved by the Effector of the feature with claim 1.
It is preferred embodiment the theme of dependent claims.
Adopt this known manner, Effector according to the present invention comprise lockable mechanism and-at least one shift rod shifting block groove moveable-gear level.At this, lockable mechanism for limiting the moving region of gear level, for certain travelling speed level position of locking gear level, or also for gear level is locked at certain shift lever position.
According to the present invention, the feature of Effector is, lockable mechanism comprises the lock groove be connected with gear level and the basic locking projection for prismatic that final controlling element (aktuatorisch) can be utilized to rotate around running shaft, wherein projection-running shaft is parallel to the longitudinal axis stretching, extension of projection, and projection is inserted in the lock groove be connected with gear level.
Obtain simple and the durable and variable lockable mechanism of reliable operation of a kind of structure in this way, it is for limiting the moving region of gear level, and/or for gear level is locked at certain shift lever position, this lockable mechanism only uses an actuator just enough.Especially, actuator can be configured to speed changer servomechanism at this, this results in additional advantage, namely independent of the position of locking projection, and independent of such as activate or the state of gear level locking of deexcitation, in no case need the work capacity for keeping lock position.
Except gear level can being locked at the moving region of certain position or restriction gear level, Effector of the present invention can also realize the whole moving region of locating gear level according to the rotary angle position of locking projection when size is constant changeably.
In addition, compared to the known lockable mechanism for gear level, obtain following advantage: when gear level may be handled, while activation lockable mechanism, the risk of inadvertently getting over the gear level locking of just having inserted can be avoided, and then avoid gear level to remain on the risk of the shift lever position of real locking.Because when inadvertently getting over gear level locking when inserting locking, gear level by be configured to rotatable projection, the lockable mechanism that sails into, get back to correct position simply.In other words, this means, lockable mechanism constructed according to the invention can also be considered as actuator, and described actuator is provided for gear level and automatically moves under certain state.
Particularly under the background of the variable position of the whole moving region of gear level, the particularly preferred mode of execution of one according to the present invention, regulation: gear level is designed to monostable fixed.
In other words, this means, be designed to monostable gear level and get back to again same neutral position all the time after each handover operation.This point is particularly conducive to the manipulation of the speed changer to line traffic control, because in this way, when being such as automatically placed in speed changer travelling speed level, such as, when being automatically placed in parking lock by " automatically-P ", particularly can saving and following the tracks of gear level electrically.Alternatively, for the gear level for this single Stability Design, only need follow the tracks of or always upgrade the indication mechanism of (aktualisieren) speed changer travelling speed level, and be matched with current transmission state.
But for driver, this means, with regard to the gear level of single Stability Design, originally only by independent indication mechanism, such as, realized the feedback of the actual switching state about speed changer by light emitting diode or displaying symbol.On the contrary, for monostable gear level, without the need to transmit the vision of the switching state about speed changer to driver by shift lever position or the feedback of sense of touch.
In addition for for the known monostable gear level of prior art, realize the switch logic of correct machinery, mechanically show the movement angle region allowed respectively of gear level and realize required speed change lever locking such as key lock or sift lock if desired, all more loaded down with trivial details, because need at present the loaded down with trivial details actuator for locking gear level selectively for this reason.
But the lockable mechanism with the locking projection of rotation used according to the invention, this also has conclusive advantage.Because by locking projection and the mating reaction being arranged on the lock groove on gear level, not only can realize limiting changeably moving region and the locking gear level if desired of gear level, but also the moving region of the permission of gear level can be positioned in the whole motion window of gear level changeably.
Latter instance is for the meaning of monostable gear level, and the neutral position be automatically placed in again all the time after handling by gear level can be assigned to actual arbitrary switching state of speed changer.
The gear level in the neutral position keeping it stable particularly can represent each standard compliant speed changer travelling speed level " P ", " R ", " N " or " D " at this.The in fact residing travelling speed level of speed changer mainly shows on gear level or on motormeter by means of only indication mechanism variable accordingly.
But due to the lockable mechanism with locking projection used according to the invention, for monostable gear level, also can with reference to the common multistable fixed behavior with the gear level of multiple stable shift lever position in following: the actual movement of gear level depends on the travelling speed level be placed in fact respectively in the transmission, or rather, for this reason without the need to locking gear level selectively.If such as insert parking lock in the transmission, then traditional gear level can not move forward other velocity stage, but usually can move three velocity stages backward, then this gear level is encountered in the backstop being positioned at opposite, parking lock position of Effector, or encounters on the opposed end of gear level chute.
According to the present invention, even if for monostable gear level, also the action meeting intuitive operation can be realized, its mode is, by the corresponding control to locking projection, the moving region of the current permission of gear level is always moved in the whole motion window of gear level, thus the direction that gear level can only be corresponding along the speed, transmission level logic with residing is correspondingly moved, and the angle corresponding with residing speed, transmission level logic can only be moved.
First the present invention realizes independent of following situation at this: how, how the operating mechanism of final controlling element that utilizes of projection is arranged for projection shape and structure.But according to particularly preferred mode of execution of the present invention, projection is arranged on cam side, and its cam is preferably made up of gear.
Structurally can realize the support to projection in this way simply; In addition the bias of projection relative to its running shaft can be changed in a straightforward manner, such as, in order to constructively make lockable mechanism adapt to different gear level motions.Cam configuration is become one of gear of the actuator of lockable mechanism, achieve the parts of execution speed changer of lockable mechanism and the function unification of the favourable of cam, and then make lockable mechanism simple especially, with low cost and durable.
According to of the present invention another preferred embodiment, lock groove to be arranged on the suspension that is connected deviously with gear level or in.According to this mode of execution, particularly can realize economical space saving, lockable mechanism is such as arranged in the region of the pedestal of gearshift by level land.
According to of the present invention another preferred embodiment, projection has substantially round shape of cross section.This design can realize inexpensively, and when projection is correspondingly arranged on cam prejudicially, still be allowed for the locking region of the multiple different size of gear level or multiple lock position, and also allow as required the moving region of gear level to be positioned at changeably in operational whole motion window.
According to the mode of execution that another substitutes of the present invention, it is polygonal shape of cross section that projection has basic.By this mode of execution, utilize same lockable mechanism, the different moving region of multiple different lock position for gear level or different in width if desired can be produced.Depending on bias or the rotary angle position of projection, from have the current different effective diameter of projection in the lock groove that gear level connects and work.Obtain lock groove and the gear level different remaining motion path relative to projection thus respectively, when by regulation restricted movement regions, these remaining motion paths can cause gear level to be locked at certain shift lever position completely.
According to another embodiment of the present invention, projection has irregular octagonal shape of cross section substantially.Based on the projection of so design, the effective bump diameter of four different sizes at the most can be realized, realize the moving region of four different in width being at the most used for gear level thus.In addition, based on the irregular shape of cross section of projection, different bump diameter can be located relative to the running shaft of projection to a great extent independently of each other, thus can in the whole motion window of gear level, the moving region of gear level is positioned to many eight different positions.
But the present invention is in no way limited to polygonal projection, described projection has the edge of some or has the different orientable bump diameter of some.Or rather, also can consider to use the locking projection with edges many arbitrarily in principle and/or effective bump diameter many arbitrarily in principle.In addition, the present invention also comprises the locking projection not having edge, this locking projection has the unmodifiable effective projection radius of continuous print substantially, and/or the present invention also comprises relevant lock groove, the cross section on the surface of this lock groove forms free curve (Freiformkurve) substantially.The location of the constructively very complicated moving region to gear level or the requirement of size variation can also be met in this way, wherein particularly can also realize the stepless location to moving region or size change.
Under this background, according to another particularly preferred mode of execution of the present invention, regulation: at least one effective diameter of projection and the consistent at the width that its corresponding rotary angle position is effectively relevant relative to projection of lock groove.In this way, particularly when there is no additional blocking element, the lock position completely of gear level can be realized simply.In order to locking gear level, only make projection be in following angular orientation, namely in this angular orientation, the effective diameter of projection and the Effective face width one of lock groove are made peace superimposed.
Another embodiment of the present invention specifies: lockable mechanism have multiple be configured to cam disk, parallel to an axis is arranged, the projection that axially adjoins each other.Because multiple cam disk is arranged abreast, other additional switching or the latch functions for gear level can be realized, the different Zone switched or locking region of such as working in the different shift rod shifting block groove of gear level.
Under this background, according to of the present invention another preferred embodiment, regulation: the second cam disk has locking projection.At this, the protruding concave shape with being arranged in lock groove of locking is complementary, and the indent wherein in lock groove is arranged on outside the stopper area of the first cam disk.
Adopt in this way, particularly in order to make gear level between different gear level fork shaft shifting block grooves, such as switch between shift rod shifting block groove and end fork shaft shifting block groove, additionally can also realize locking by same Locking Device or allow the side of gear level to move.In order to such as allow gear level to switch to end fork shaft shifting block groove from shift rod shifting block groove, projection or the cam with cam disk only rotate to such as upper/lower positions, and namely in this position, the locking of the second cam disk is protruding superimposed with the indent in lock groove.Now, gear level can move to end fork shaft shifting block groove at side from shift rod shifting block groove together with lock groove, and wherein the locking projection of the second cam disk can in the indent of side in lock groove.On the contrary, in other rotary angle position all of cam disk, the locking all by the second cam disk is protruding, and locking gear level moves to end fork shaft shifting block groove at side from shift rod shifting block groove.

Figure 14 is the view corresponding to Figure 10 to 13, and it illustrates locking projection according to Figure 10 to 13 and lock groove, and wherein locking projection is in middle position " N ".
Fig. 1 is the schematic side view of a mode of execution according to Effector of the present invention.First just can see the only gear level 1 shown in local and the lock groove 2 that is connected with gear level 1 quickly.Gear level 1 and lock groove 2 are interconnected, and swingable relative to the pedestal 4 of Effector by swing axis 3.Illustrated embodiment is the Effector with monostable gear level 1.This means, gear level 1 is when around the neutral position beat of its central authorities shown in Fig. 1, and spring loads ground and gets back to again this neutral position all the time.
In addition can see columniform locking projection 5, it is arranged on and is configured on the cam 6 of gear simultaneously.Cam 6, by small gear 7, is driven by electronic execution driving mechanism 8.Adopt in this way, the locking projection 5 be positioned at prejudicially on cam 6 can be in different positions relative to lock groove 2.In FIG, locking projection 5 is in its highest position.This position of locking projection 5 is corresponding with parking lock (Parksperre) residing in automotive transmission.In other words, this means, when being in parking lock in automotive transmission, can manually or automatically make locking projection 5 move to the extreme higher position shown in Fig. 1 by execution driving mechanism 8 all the time.
From the angle of operator or driver, this means, when being in parking lock, gear level cannot continue to move forward, and this is represented by thick dotted line 9.On the contrary, with regard to illustrated embodiment, gear level 1 can from parking lock position backward (be with drawing benchmark to the right) move to many two travelling speed level positions, such as to select reverse gear shift " R " or middle position " N " thus.This motion of gear level 1 in FIG with prismatic the motion angle 10 that highlights represent, this motion angle 10 is corresponding with the freedom of movement 11 of the same angular dimension of locking projection 5.In other words, this means, the relative position of locking projection 5 in lock groove 2 had both determined the temporary transient terminal backstop 9 of gear level 1 in the whole operational window 12 moved for gear level in a variable manner, determined again the temporary transient moving region 10 of gear level 1.
Except by except the location to the terminal backstop 9 of gear level 1 and the active of moving region 10, also by optics indication mechanism 13 variable accordingly, inform there being the current handoff state of manual transmission to be controlled to user.Described switching state is the current residing travelling speed level position (parking lock " P " namely in Fig. 1 or the driving travelling speed level " D " in Fig. 3) be apprised of respectively in optics indication mechanism 13, and selectable adjacent transmission gear is not spatially assigned to the certain position relative to speed change toggle link (Schaltkulisse) 14 regularly respectively, or rather, but relative to keeping the gear level 1 of intermediate position all the time, control variable accordingly and display are carried out to temporarily residing travelling speed level position and adjacent transmission gear.In other words, this means,-be different from common there is stable shift lever position gear level-, residing gear is not shown relative to the moveable gear level of fixed scale, on the contrary, or rather, this task is born relative to the moveable scale 13 of fixed gear level 1 by that control changeably, that is virtual.In FIG, the representation of this point is as follows: the temporary transient unactivated region shown in the imaginary point of gear indication mechanism 13 is equipped with one of possible transmission gear equally.
The Production conditions of the situation shown in Fig. 2 is: gear level 1 moves to middle position from the parking lock position according to Fig. 1.Locking projection 5 and lock groove 2 mating reaction, same responsible appreciable terminal backstop 9, but be when gear level 1 is handled specifically.After gear level 1 departs from the position according to Fig. 2, the neutral position according to Fig. 1 got back to again by gear level 1.But in this case, by the electronic control mechanism of Effector, gear indication mechanism 13 is simultaneously correspondingly servo-actuated, thus gear level get back to its according to the neutral position of Fig. 1 after, and for example with the same travelling speed level " N " correctly residing for display now in the past.
Meanwhile, by actuator 8, locking projection 5 is also correspondingly servo-actuated to the relative position corresponding with shift lever position " N ".Described relative position is represented by the position 15 of the locking projection 5 in Fig. 1 shown in imaginary point, this relative position-consistent with now residing transmission gear " N "-thus allow gear level to be benchmark relative movement to the right velocity stage with drawing, or be benchmark relative movement left two velocity stages with drawing.
Give the situation being similar to Fig. 1 and 2 in figs. 3 and 4, difference is, not as in the past, from " P " to " N " switched in figures 3 and 4, but switched to reverse gear " R " from travelling speed level " D ".Originally-according to Fig. 3-, the relative position of locking projection 5 in lock groove 2 also determine gear level 1 towards travelling speed level " R ", according to temporarily residing travelling speed level " D " operational moving area 10 (consistent relative to the moving area 11 of locking projection 5 with lock groove 2), and determine gear level 1 along the rightabout terminal backstop 9 temporarily worked towards " D " because being in direction of travel is that benchmark is positioned at rearmost (being that benchmark is positioned at the most right side with drawing) transmission gear " D ".
If mobile from travelling speed level " D " to " R " according to the gear level 1 of Fig. 4, then this point also triggers corresponding switching command first quickly in manual transmission.When next gear level gets loose, this gear level bounces back into again its neutral position according to Fig. 3, wherein by the electronic control mechanism of Effector, gear indication mechanism 13 also corresponding to gear level 1 rollback motion and servo-actuated, and the rotational position of simultaneously correspondingly adaptive adjustment locking projection 5, thus next locking projection 5 is in the position 16 in figure 3 shown in same imaginary point.
Fig. 5 illustrates another mode of execution of Effector of the present invention.Effector shown in Fig. 5 be particularly, according to the Effector of Fig. 5, there is erose, eccentric rotate, polygonal locking projection 17 according to the difference of the Effector of Fig. 1 to 4.In addition also can see swing axis 3 in Figure 5, gear level 1 together with connected lock groove 2 relative to pedestal 4, and can swing around described swing axis relative to locking projection 17.In addition, Effector according to Fig. 5 also comprises gear indication mechanism 13, described gear indication mechanism 13 with in the whole motion window 12 of gear level 1 variably location or control, for the optics indication mechanism of each travelling speed level " P ", " R ", " N " and " D ".
In addition, a particularity of the Effector shown in Fig. 5 is, in this embodiment, there is the cam or cam disk that arrange before and after multiple axially (namely perpendicular to drawing).Except locking projection 17, particularly also there is another take drawing as the cam disk that benchmark is arranged on after locking projection 17.This another cam disk particularly has locking projection 18 at this, and wherein this locking projection 18 forms the additional lockable mechanism being used for gear level together with indent 19.At this, indent 19 is arranged on for outside the surface of contact of locking projection 17 or stopper area, described surface of contact or stopper area are above and below benchmark is arranged in lock groove 2 with drawing, thus in lock groove 2, can not interference be produced between locking projection 17 and the different latch functions of cam disk 18.
Adopt in this way, utilize same lockable mechanism, or only utilize the final controlling element that is electronic, except the moving area of gear level 1 is affected, the motion of (taking automobile as benchmark) side that may exist of locking or permission gear level can also be realized in addition.Thus this additional latch functions particularly can be considered for locking or allow the side gearshift of the m-m-exchange pin such as in shift rod shifting block groove and end fork shaft shifting block groove (Tipgasse) at different shift rod shifting block grooves.
Therefore for gear level 1, in order to such as allow to switch to end fork shaft shifting block groove from shift rod shifting block groove, projection axle 20 only need be made to rotate to as upper/lower positions, namely in this position, locking protruding 18 is superimposed with the indent 19 in lock groove 2.Next, gear level 1 (together with lock groove 2) can be moved to end fork shaft shifting block groove at side from shift rod shifting block groove.At this, the locking projection 18 of the second cam disk can in the indent 19 of side in lock groove 2.On the contrary, in other rotary angle position all of locking projection 17 or projection axle 20, gear level moves through the locking projection 18 of the second cam disk by locking from shift rod shifting block groove to the side of end fork shaft shifting block groove, because in these cases, locking projection 18 is that benchmark is encountered on lock groove 2 from behind with drawing, and (or take automobile as benchmark along transverse direction) motion that thus lock groove 2 enters into drawing obtains locking.
First Fig. 6 corresponding to the embodiment according to Fig. 5 illustrates the relative position of locking projection 17 and lock groove 2, and for being in parking lock " P " situation, the gear level 1 be connected with lock groove 2 is shown.In this case, the light-emitting component " PRND " of gear indication mechanism 13 in whole motion window 12 operational for gear level 1-relative to remaining that the gear level 1-of intermediate position is activated or location by the electronic control mechanism of Effector changeably, thus light-emitting component " PRND " is consistent with the parking lock " P " in the transmission residing for reality relative to the position of static gear level.
In addition, the variable stop mechanism be made up of locking projection 17 and lock groove 2 of gear level 1 is also controlled by the corresponding rotation of locking projection 17, thus the parking lock " P " of actual operational toggle path 10 also with temporarily residing is logically consistent on gear level 1.In other words, this means, although gear level 1-is configured to monostable fixed, thus intermediate position-the same with the common multistable fixed gear level being in parking lock position is remained, can not be continued to move forward by operator, but many three stage of switches can be switched to simultaneously backward, that is, gear level 1 (or with drawing be benchmark to the right) can move to travelling speed level " D " backward, and non-forward (or be with drawing benchmark left) is mobile.
Whether this has nothing to do with following situation for shown Effector: be manually such as be placed in parking lock, or be automatically placed in parking lock.Because, this situation of parking lock is automatically placed in for from one of travelling speed level or from middle position " N ", the electronic control mechanism of Effector also both can design the light-emitting component " PRND " of gear indication mechanism 13 from motion tracking ground, latch design projection 17 again, thus on gear level 1, produce the corresponding vision (gear indication mechanism 13 shows speed, transmission level " P ") and the sense of touch (moving region 10 and terminal backstop 9 are corresponding to speed, transmission level " P ") that belong to parking lock position.Although be such as such as automatically placed in parking lock when automobile leaves, driver still can find the relative position between gear indication mechanism 13 and gear level 1 thus when moveing backward and when resetting, and finds the terminal backstop of the gear level consistent with residing position " parking lock ".
The operational moving region 10 of gear level 1 is determined by the free space 11 formed between locking projection 17 and the lower edge of lock groove 2 at this, for the ease of identifying, in figure 6-also indicate corresponding prismatic with the same-this free space 11 in moving region 10 itself.On the contrary, along the direction contrary with moving region (namely with drawing be benchmark left, or by automobile forward) the temporary transient terminal backstop 9 of gear level 1 be made up of the locking projection 17 on the upper edge abutting in lock groove 2 in this case.
Other three travelling speed level positions " N " of gear level 1, the situation of " D " and " R " are similar to for the situation shown in parking lock position " P ".The relevant position of the relevant position of locking projection 17 and the light-emitting component " PRND " of gear indication mechanism 13 is shown respectively in Fig. 7,8 or 9.
In the figure 7, travelling speed level " N " is placed in the transmission.Therefore, by the electronic control mechanism of Effector, make on the one hand the light-emitting component of gear indication mechanism 13 " PRND " relative to gear level 1 or be in relative to speed change toggle link 14 consistent with travelling speed level position " N " gear level 1 or the relative position relative to speed change toggle link 14, on the other hand locking projection 17 is rotated, until produce corresponding distance or movement angle 11 (indicating prismatic in the drawings) and 11 ' (indicating criss-cross in the drawings) between locking projection 17 and lock groove 2.Movement angle 11 and 11 ' is based on the connection be integrated between lock groove 2 and gear level 1 herein, be delivered on gear level 1 pro rata, form the operational motion scheme 10 (also indicating prismatic in the drawings) in travelling speed level position " N " residing for temporarily and 10 ' (also the indicating criss-cross) of gear level 1 thus.
The situation of the relevant travelling speed level position " R " shown in Fig. 9 is quite analogous in the figure 7 for the situation shown in travelling speed level position " N ".Between situation in Fig. 9 and Fig. 7, only there is the following main distinction: locking projection 17 have rotated 180 °, thus is different from Fig. 7, the movement angle of lock groove 2 11 and 11 ' or the movement angle 10 and 10 of gear level 1 there is contrary ratio.In addition, the location matches of the light-emitting component " PRND " of gear indication mechanism 13 in the travelling speed level position " R " residing for reality, and is moved in whole motion window 12 by the corresponding control to the light-emitting component of correspondence.
The situation of the relevant travelling speed level position " D " shown in Fig. 8 is substantially corresponding to being placed in the position in parking lock situation shown in Fig. 6, and difference is: locking projection 17 have rotated again 180 ° relative to the parking lock position in Fig. 6 in fig. 8; And the position of the light-emitting component of gear indication mechanism 13 " PRND " is also correspondingly mated in motion window 12.By the rotational position of the corresponding change of locking projection 17 in lock groove 2, for gear level 1 forward or be the movement angle 10 or 11 that benchmark obtains three levels consistent with travelling speed level position " D " left with drawing, and backward or be that benchmark obtains to the right with the locking to gear level 1 shown in dotted line 9 simultaneously with drawing.
Put " D " equally in fig. 8 or at traveling velocity stage thus, no matter gear indication mechanism " PRND " is relative to the relative position of gear level 1, or the motion of the actual capabilities of monostable gear level 1, all consistent with situation about presenting for traditional multistable fixed gear level with stable shift lever position.
Finally, in Figure 10 to 14, the lockable mechanism of another mode of execution of Effector of the present invention is shown in very schematic mode.Equally also erose polygonal locking projection 17 here can be seen respectively, this locking projection 17 is at its different rotational position according to Figure 10 to 14, for lock groove 2, thus also for (unshowned) gear level 1 be connected with lock groove 2, different right movement angle 10 and 10 ' or 11 and 11 ' (see Fig. 7 or 9) is each provided here.
Particularity according to the mode of execution of Figure 10 to 14 is particularly, locking projection 17 can not only be in four different rotational position at this, and five different rotational position can be in, in these positions, locking projection 17 each provides different effective diameters 21, or provides the different relative position in lock groove 2 of the effective diameter 21 of its difference.
5th additional rotary angle position " X " of locking projection 17 is particularly shown in fig. 12 highlightedly at this.In the 5th rotary angle position according to Figure 12, locking projection 17 has effective diameter D relative to lock groove 2, and this diameter D is consistent with the clear span of lock groove 2.
In other words, this means, different four pairs of movement angles 10 and 10 ' or 11 and 11 ' (see Fig. 7 or 9) is provide not only according to the lockable mechanism of Figure 10 to 14, be intended to correctly control gear level 1 in sense of touch, but also the 5th rotary angle position of the locking projection 17 according to Figure 12 can be used, be provided for gear level and be locked at certain position completely, such as to inform driver by sense of touch thus: automobile or the unripe work of speed changer, or be still in safe lock.
Result clearly thus, and adopt and the invention provides a kind of Effector with lockable mechanism, it has the following advantages relative to prior art tool: under locking task complicated situation, and it uses the final controlling element of minimum number also can deal with.Adopt structure especially simply, the design form of thus cost-effective design form and energy conservation, achieve additional advantage.In addition, the lockable mechanism of Effector of the present invention also can be considered for the location freely changed to the moving region of gear level or change, and is also considered for the motion utilizing final controlling element of gear level if desired.
In this way, and exactly for current monostable Effector, the present invention can realize for the driver's switching state of the reliable reality about such as automatic transmission and tactile feedback of current motion scheme all the time.
Due to cost-effective realizability and higher functional reliability, the present invention is to the Effector improving automotive transmission, and the travelling comfort particularly in the application of the high request in automatic transmission field, man-machine harmony and Security made conclusive contribution.
